上述步骤 S01中具体可以包括:
步骤 SO 11, 接口单元 10搜索整个网络, 获取可访问的网元基本信息; 网元的基本信息包括网元的名称和 IP地址; 用户选择至少一个要还原的网 元, 检查用户所选的网元是否存在 ip沖突, 网元名称重复, 网元不能访问 等问题, 若有, 则发送错误信息给接口单元, 接口单元 10提示错误信息; 若上述问题不存在, 则将网元的基本信息发送至选择单元 20。
步骤 S012 , 接口单元 10把可访问的网元的基本信息发送给选择单元 20, 查询各网元的 ASON运行状态, 若有网元 ASON运行状态不正常, 反 馈模块 23发送信息给接口单元 10,接口单元 10显示提示信息: "如下网元 ASON运行状态异常" , 并附上 ASON运行状态异常的网元的基本信息; 步骤 S013 , 根据上述各网元的 ASON运行状态筛选出要最终要还原的 网元; 例如, 可剔除 ASON运行状态异常的网元, 选择 ASON运行状态正 常的网元进行还原操作; 也可保留 ASON运行状态异常的网元, 对其进行
还原操作。
步骤 S014, 接口单元 10发送指令给存储单元 30, 获取所述要还原网 元可选的还原点, 即备份操作时的时间戳。
上述步骤 S04中, 接口单元 10把要还原网元的信息、 以及还原点信息 发送给还原单元 50, 还原单元 50从存储单元 30提取所述要还原网元还原 点时刻的 ASON数据,通过网元接口访问所述要还原网元并用查到的 ASON 数据覆盖所述要还原网元当前的 ASON数据。 覆盖完成后, 还原单元 50通 知接口单元 10还原操作成功, 接口单元 10显示 "还原操作成功, 是否重 启 ASON程序" 的提示信息。
一般来说, ASON数据改变后, 需要重启 ASON程序, 新的库文件才 能生效。 因此, 当系统接收到接口单元 10 "还原操作成功, 是否自动重启 ASON" 的提示后, 若选择 "是", 则 ASON自动重启, ASON再次运行, 还原操作生效; 若选择 "否", 可推后重启 ASON, 使还原操作生效。
以上所述仅为本发明的较佳实施例而已, 并不用以限制本发明, 凡在 本发明的精神和原则之内所作的任何修改、 等同替换和改进等, 均应包含 在本发明的保护范围之内。
